Missing a few on this list for the "tranquil" side of things. (It's a pun, get it?) 1) Sigur Ros: I think "( )" is my prefered altered state soundtrack. "Agaetis Byrjun" is a pretty intense album but not quite the whole package. 2) Eluvium: Instrumental music, piano-centered. Think George Winston or Philip Glass for 20-something's. "Copia" is a great start. 3) Radiohead: "OK Computer" if you've got a killer soundsystem or plan on wearing headphones because it was made to be heard in stereo. I have probably listened to the album well-over a few hundred times since it came out 10 years ago but "heard" it for the first time at a planetarium lazer show up in Portland a few years ago. I left with my hears ringing the hardest in my life and with a brand new appreciation of the album. 4) Mogwai: Albums of pure noise or Sigur Ros minus the alien vocals. Too bad their albums can't match their live sound. 5) Portishead: "Dummy." Nothing more to say. While I'm a big fan of stoner rock I've never been able to equate it to being in an altered state. Maybe uppers would work better.

I agree with pretty much everything that's been posted, but this strikes me as a weird choice, and not just because it's a weird choice, but because I thought of it when I was posting my initial list. I saw them at Black Cat and it was a completely different experience than their record; very dirty and was actually kind affecting for me, blissed out on about eight PBRs.

I'd like to split hell wide open by recommending the screwed/chopped version of motherfucking "Rainbow Colors" by Three Six Mafia. Get some decent speakers with sub-woofers and enter into the head space. When complete, move on to "Half on a Sack." Segue into "Why Don't You Eat Carrots?" by Faust.

I'm starting this right now. Will check back if I make it through alive.
